Abstract: Battery thermal management is becoming more and more important with the rapid development of new energy vehicles. This paper presents a novel cooling structure for cylindrical power batteries, which cools the battery with heat pipes and uses liquid cooling to dissipate heat from the heat pipes.
The system involves submerging the batteries in a non-conductive liquid, circulating the liquid to extract heat, and using an external heat exchanger to further dissipate it. This provides a closed loop immersion cooling system for the batteries. The liquid submergence and circulation prevents direct air cooling that can be less effective.
By changing the surface of cold plate system layout and the direction of the main heat dissipation coefficient of thermal conductivity optimization to more than 6 W/ (M K), Huang improved the cooling effect of the battery cooling system.
